There's lots of things that escape XactReadOnly. I've thought (and I
think suggested) before that we should put in another layer of defense
by also putting a check in AssignTransactionId(). Imo the compatibility
woes (like not being able to run SELECT txid_current();) are well worth
the nearly ironclad guarantee that we're not writing.
